  1. CVE 312 TRANSPORTATION ENGINEERING

  2. INTRODUCTION • Teaching Approach & Grading Policy • Course Outline • Introduction to Transportation Engineering • Modes of Transportation systems-Land, Air & Water transportation systems

  3. Introduction to transportation engineering • Importance of transportation in economic development of a nation • Career opportunities in Transportation Engineering • Involvement of Civil Engineers in Transportation Engineering • Transportation as an inter-discipline related subject • Transportation management system in Nigeria

  4. Modes • Different modes in Transportation- railroad; airway; highway; waterway; belt conveyor; pipeline • Intrinsic features of different modes • Classification-Unit of carriage; Guidance & manoeuvrability; Buoyancy & stability • Characteristics of Vehicles used in Transportation-highway, Aircrafts, Water-borne vessels & Railroad vehicles • Components- Motive power, way or travel medium

  5. Rail track analysis • Track structure: Overall track structure typically consists of sub grade, ballast, ties, rails and rail fastenings. • Ballast: has a number of functions which include; • Distribute tie loads to the sub grade • Anchoring track against lateral, vertical & longitudinal movement • Providing for drainage of water away from rail &ties • Ties are used to maintain gauge and to transmit wheel loads from the rails to the ballast

  6. Waterways • Natural waterways sometimes serves as travel ways without any intervention but sometimes require extensive intervention. • Dams & Locks- when sufficient depth of flow is not otherwise available, storage reservoirs are used to provide artificial pools and slack water navigation. Thus, dams and locks are used to obtain navigable channels over water whose flow would not otherwise support navigation. • Requirement for lock & dam

  7. Ports and harbours • These are simply the terminal facilities for the water mode. • Harbour is a partially enclosed area of water which serves as a place of refuge for ships while loading, unloading or being serviced. It provides a safe anchorage and protects ships from waves of the open seas. • Features for Harbour sites • Port- is that portion of the harbour which serves as a base for commercial activities. • Planning & design of port facilities

  8. Highway • Pavement Structure • Sub grade: is usually the natural material located along the horizontal alignment of pavement and serves as the foundation of the pavement structure. • Sub base: located immediately above the sub grade • Base course: lies immediately above the sub base • Functions/ Standard requirement

  9. Rail road’s signals & traffic control • At all times, rail locomotives remain under a high degree of control- since their paths are restricted by the tracks. • Definitions of Side-tracks, turn-out, switch, etc. • Types of switch- Stub switch, split switch • Railroad signal system- the two principal signals used for control are- semaphore blades & light signals • Train control system can be categorised into the following classes: Time table/ train order; Automatic block system & Centralized traffic control • Yard: receiving, classification & departure

  10. Air terminals These include portions of airports other than the landing and take-off areas i.e. car-parking lots, aircraft parking aprons, terminal buildings and facilities required for inter-terminal as well as intra-terminal transportation. • Functional elements that can be identified in airport passenger terminals- airside, terminal building & landside • Layout concepts • Vehicle parking needs • Aircraft parking needs • Space Requirement for Terminal building
